Organic farming is an eco-friendly agriculture practice that promotes the sustainable use of natural resources and the preservation of the environment. It involves avoiding the use of synthetic fertilizers, pesticides, and genetically modified organisms (GMOs), and instead focuses on using natural methods to enhance soil fertility, control pests and diseases, and promote biodiversity.

Advantages of Organic Farming:
1. Environmental Benefits: Organic farming practices prioritize the conservation and protection of soil, water, and air quality. By avoiding the use of synthetic inputs, organic farmers prevent the contamination of groundwater and reduce the release of harmful chemicals into the environment. They also promote the use of renewable resources and minimize the carbon footprint associated with agriculture.

2. Improved Soil Health: Organic farming relies on practices such as crop rotation, composting, and the use of organic manures to enhance soil fertility. These practices promote the development of a healthy soil ecosystem, with increased microbial activity, improved nutrient availability, and better water retention. Organic soils also have higher organic matter content, which helps in carbon sequestration and mitigating climate change.

3. Biodiversity Conservation: Organic farming encourages the conservation of natural habitats, which in turn supports a diverse range of plant and animal species. Organic farms often have higher levels of biodiversity, including beneficial insects, birds, and pollinators, due to the absence of chemical pesticides and the presence of diverse crop rotations and hedgerows.

4. Health Benefits: Organic farming aims to produce food that is free from synthetic chemicals, hormones, antibiotics, and GMOs. Organic produce is considered to be healthier as it has higher levels of beneficial nutrients such as vitamins, minerals, and antioxidants. It also reduces the risk of exposure to pesticide residues, which can have negative effects on human health.

5. Sustainable and Economic Viability: Organic farming promotes the long-term sustainability of agricultural systems by reducing dependence on external inputs and improving the resilience of farming communities. Organic farmers often adopt practices that enhance resource efficiency, reduce waste, and increase profitability.

In conclusion, organic farming is an eco-friendly agriculture practice that promotes environmental sustainability, soil health, biodiversity conservation, and human health. It is a holistic approach to farming that emphasizes the use of natural resources and the protection of the environment, making it the most suitable option among the given choices.
